■ Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires , make sure to cancel the
power back door system ( �P . 182 ). Failure to do so may cause the back door to operate
unintentionally if the power back door switch is accidentally touched , resulting in hands and
fingers being caught and injured .
2 Align a wheel bolt hole on the tire with the guide pin , and set the tire on the guide pin .
Securely set the tire so that its wheel is touching the contact surface .
